ICAR Technical Series No 3 The development of the Dorper sheep and the Improved Boer Goat are undoubtedly two of the most successful long-term livestock programmes in South Africa. The Dorper is a composite mutton sheep breed developed through crossing an indigenous breed with a British mutton breed and the Improved Boer Goat was developed using a breeding strategy based largely on selection fo...

The Qira black sheep and the Hetian sheep are two local breeds in the Northwest of China, which are characterized by high-fecundity and low-fecundity breed respectively. The elucidation of mRNA expression profiles in the ovaries among different sheep breeds representing fecundity extremes will helpful for identification and utilization of major prolificacy genes in sheep. In the present study, ...

Background: The Lori-Bakhtiari sheep breed is one of the most common native breed in the south-western parts of Iran. The peri-parturition period (2 weeks before to, 2 weeks after parturition), is generally of critical importance regarding the health, production and profitability of the ewes. OBJECTIVES: This study was carried out to compare the serum concentrations of glucose, non-esterified f...

Quality carcass and non-carcass are two inseparable components that result from slaughtering animals with high economic value. The aims study is effect of polimorfisme DGAT1 gene on hot cold carcass, neck traits in Indonesia sheep. A total 50 rams used this were collected 10 Barbados Cross Sheep (BCS), Compass Agrinac (CAS), 15 Javanese Thin-Tailed (JTTS), Jonggol (JS). sheep slaughtered at 10-...

Leptin (LEP), the expression product of the obese gene produced primarily in the adipose tissue, is related to feed intake, growth and lipid metabolism. The aim of this study was to study the possible association between polymorphism of the LEP gene with growth and carcass traits among three Iranian sheep breeds of the Shal, Zandi and Zel varieties. A total of 180 purebred animals of the Shal, ...

kermani sheep breed is one of the major sheep breeds in iran, especially in kerman province for which no study has yet been carried out through y-chromosome specific microsatellite markers. throughout this study, amplification quality related to 17 bovine y-chromosome specific microsatellites was evaluated for the mentioned sheep breed. one hundred males and twenty females of non-related animal...
